2.5 / Area management

* Add Area Swap: hold alt and drag with LMB from either actionzone. Release LMB on area you want to swap with. I added a matching cute cursor for this (and to make it a politically delicate issue, it's white on black).
  Note, there are still some error totblocks that I haven't been able to track down properly yet, so that's still a bit WIP.
